Which one? COSMOS isnt the best cfd package, but its easy to use. I really want to switch over to OpenFOAM since it should make more accurate simulations than COSMOS but I'm scared by the supposed difficulty of all the meshing options.

:dunno: Looks like all I have a licence for at work is static FEA at the moment. I should have a seat for EVERYTHING but dealing with the computer guy here at work is not a good use of my time. I know my home desktop has it all turned on, I can check when I get there, but it's whatever is packaged within solidworks. It wasn't cosmos, and I don't know how to use it properly. I can get pretty pictures but garbage in, garbage out.

Honda manifold makes more power everywhere provided the runners are long enough. The trick is getting the runners the correct length, aligning them with the ports and clearing everything on the coldside of the engine bay. I have yet to build one I'm really satisfied with. Kicking around the idea of giving up on aluminum protos (expensive) and just printing one. One of the engineers I consult for various projects can draw it. Several SLA printing facilities nearby. Yup, that's what I need to do.

Regarding the cold air intake.... Where does the filter end up at? Just can't visualize the net results based on your post.

I have a cone filter over on the hot side of the bay now and 130 deg intake temps on a NA engine aren't helping anything.

Thanks

Disclosure, I've never run the same one for more than 10 hours.

An SLA printed manifold would survive dyno time, no problem.

That said, if you can print and intake manifold, you can print a mold. And if you can print a mold, I can get flanges made and make a bitchin carbon fiber manifold. This would be a much better solution than wrapping the printed manifold.

Oh an SLA plastic manifold could survive dyno time, even at 1/8" wall (1/4" is fine). But 1 intake backfire and it'll be in pieces, ask me how I know.

CAI (Cold Air Intake), cold side. Really, don't over think it. Bend it to towards the cold side somewhere. It is not rocket science.

This is off-topic (ish), but when I get my car re-tuned over winter I'm going to do some back-to-back testing of air intakes.

1. Hot side intake with Track Dog Racing exhaust blanket + heatshield over by the headlight using a 3" AEM Dryflow (3" all the way to the elbow before the Skunk2 TB)

2. A Joefis Racing style 3D printed intake over the radiator into the bumper, should be 2.75" or 2.5" piping

Any updates on the whole header dyno comparison? Still waiting on the maruha to show up?

I mean, if you seriously want a price it'd be around $1200, maybe more.

Thread hijack much?

Speaking of thread-jacking... do you guys do alignments at 949 racing?

I heard Sonny did an alignment there for one of the Miata guys.

:party:

Also. Do you have any 1.6 clutches in stock?
Or 15x8" 6ULs?

We are building it for 13.5:1 compression as that is sort of the sweet spot for E85. On paper at least, it should make 215whp.

I think I know the answer
 
Okay, dumb question but is this entire exercise in getting to the golden prize of 200+ NAwhp is still within the constraints of a certain racing class?

I completely get the "because it's there" scenario (please see Catfish for more information), but is this just to see how much you can wring out of a naturally aspirated NB mill?

Genuinely curious.

Guessing here...
its in a odd place really. A dyno reclass into PTC would probably get you somewhere below 200, but you would need a good bit more than 200whp to run in PTB. a points car in either of those classes probably doesn't make sense since its going to be outclass based on tires alone. Its possible for a dyno reclass into PTB, but I doubt that.

Not sure about SCCA classing.

I think its just a fun project car, then probably sell it afterwards.

First post.

I think Emilio just wants to prove it can be done.
